NOTE
ENGLISH
Avoid keeping a fixed image on the set’s screen for prolonged periods of time. The fixed image may
yy
become permanently imprinted on the screen. Use a screen saver when possible.
There may be interference relating to resolution, vertical pattern, contrast or brightness in PC mode.
yy
Change the PC mode to another resolution or change the refresh rate to another rate or adjust the
brightness and contrast on the menu until the picture is clear. If the refresh rate of the PC graphic
card can not be changed, change the PC graphic card or consult the manufacturer of the PC graphic
card.
The synchronization input waveform for Horizontal and Vertical frequencies are separate.
yy
Connect the signal cable from the TV output port of the PC to the RGB IN (PC) port of the TV or the
yy
signal cable from the HDMI output port of the PC to the HDMI IN port on the TV.
Connect the audio cable from the PC to the Audio input on the TV. (Audio cables are not included
yy
with the TV).
If using a sound card, adjust PC sound as required.
yy
If the graphic card on the PC does not output analogue and digital RGB simultaneously, connect only
yy
one of either RGB IN (PC) or HDMI IN to display the PC output on the TV.
If the graphic card on the PC does output analogue and digital RGB simultaneously, set the TV to
yy
either RGB or HDMI. (The other mode is set to Plug and Play automatically by the TV.)
DOS mode may not work depending on the video card if you use an HDMI to DVI cable.
yy
If you use too long an RGB-PC cable that is too long, there may be interference on the screen. We
yy
recommend using under 5 m of cable. This provides the best picture quality.
CHILD SAFETY:
It Makes A Difference How and Where
You Use Your Flat Panel Display
Congratulations on your purchase! As you enjoy your new product, please
keep these safety tips in mind:
THE ISSUE
• The home theater entertainment experience is a growing trend and
larger flat panel displays are popular purchases. However, flat panel
displays are not always supported on the proper stands or installed
according to the manufacturer’s recommendations.
• Flat panel displays that are inappropriately situated on dressers,
bookcases, shelves, desks, speakers, chests or carts may fall over and
cause injury.
THIS MANUFACURER CARES!
• The consumer electronics industry is committed to making home
entertainment enjoyable and safe.
TUNE INTO SAFETY
• One size does NOT fit all. Follow the manufacturer’s
recommendations for the safe installation and use of your flat panel
display.
• Carefully read and understand all enclosed instructions for proper
use of this product.
• Don’t allow children to climb on or play with furniture and television
sets.
• Don’t allow place flat panel displays on furniture that can easily be
used as steps, such as a chest of drawers.
• Remember that children can become excited while watching a
program, especially on a “larger than life” flat panel display. Care should be taken to place or install the display where it cannot
be pushed, pulled over, or knocked down.
• Care should be taken to route all cords and cables connected to
the flat panel display so that they cannot be pulled or grabbed by
curious children.
WALL MOUNTING: IF YOU DECIDE TO WALL MOUNT
YOUR FLAT PANEL DISPLAY, ALWAYS:
• Use a mount that has been recommended by the display
manufacturer and/or listed by an independent laboratory (such as UL, CSA, ETL).
• Follow all instructions supplied by the display and wall mount
manufacturers.
• If you have any doubts about your ability to safely install your flat
panel display, contact your retailer about professional installation.
• Make sure that the wall where you are mounting the display is
appropriate. Some wall mounts are not designed to be mounted to
walls with steel studs or old cinder block construction. If you are unsure, contact a professional installer.
• A minimum of two people are required for installation. Flat panel displays can be heavy.
